float h = dht.readHumidity(); // Read temperature as Celsius (the default) float t = dht.readTemperature(); // Read temperature as Fahrenheit (isFahrenheit = true) float f = dht.readTemperature(true); // Check if any reads failed and exit early (to try again). if (isnan(h) ||...
Learn how to use temperature and humidity sensor with Arduino, how to connect DHT11 or DHT22 temperature and humidity sensor to Arduino, how to program Arduino step by step. The detail instruction, code, wiring diagram, video tutorial, line-by-line code
Temperature distributionCondensation is a ubiquitous phenomenon which depends on several factors, ranging from the degree of subcooling to the relative humidity of the condensing environment. Characterizing condensation in experimental setups, therefore, requires a proper control strategy of operating ...

Keyestudio DHT22 (AM2302)Temperature and Humidity Sensor for Arduino Uno r3,Temperature Sensor,Sensors
Arduino library for DHT temperature and humidity sensor. AVR optimized Description The DHT11, 21, 22, 33 and 44 are relative inexpensive sensors for measuring temperature and humidity. This library can be used for reading both values from these DHT sensors. The DHT11 only returns integers (e....

And then created an instance for the DHT library. #define DHTTYPE DHT22 Adafruit_SSD1306 display = Adafruit_SSD1306(128, 64, &Wire, -1); unsigned long delayTime; uint8_t DHTPin = 2; DHT dht(DHTPin, DHTTYPE); float Temperature; float Humidity; float Temp_Fahrenheit; Next, we have ...
我们创建了两个函数:一个是读取温度(读取DHT温度()) 和另一个读取湿度 (读DHTHumidity()). StringreadDHTTemperature(){ // Sensor readings may also be up to 2 seconds 'old' (its a very slow sensor) // Read temperature as Celsius (the default) ...
